Abstract

La présente invention se rapporte à un procédé et à un appareil de lecture de vidéo. Ledit procédé consiste à : en réponse à la détection du fait qu'un client cible affiche une page prédéfinie, acquérir des premières informations de configuration d'au moins une vidéo cible associée à la page prédéfinie et des informations de mise en mémoire tampon locales du client cible, les premières informations de configuration comprenant des informations d'identifiant de la vidéo cible, les informations de mise en mémoire tampon locales du client cible comprenant des informations d'identifiant d'une vidéo qui a été mise en mémoire tampon par le client cible ; en fonction des premières informations de configuration et des informations de mise en mémoire tampon locales, déterminer un état de mise en mémoire tampon de vidéo du client cible, l'état de mise en mémoire tampon de vidéo étant utilisé pour indiquer une progression de mise en mémoire tampon du client cible pour l'au moins une vidéo cible ; télécharger, selon l'état de mise en mémoire tampon de vidéo, au moins une vidéo cible dont la mise en mémoire tampon n'a pas été achevée ; et en réponse à une opération d'utilisateur, lire l'au moins une vidéo cible. Ainsi, une mise en mémoire tampon préalable d'une vidéo est obtenue, ce qui réduit la probabilité de papillotement de vidéo pendant un processus de lecture, et permet une visualisation régulière et claire de vidéos sur réseau pour des clients.
